It is quite evident, admitting that such a change is capable of producing an amount of cerebral irritation sufficient to develop well-marked cephalalgia, that the latter must of necessity be within certain limits continuous.

The views therein expressed are remarkable for their succinct and thoroughly scientific elucidation of the two great physiological principles involved in the consideration of by far the greater majority of instances of cephalalgia.

Accepting the propositions, then, that the more adjacent causes of headache are (1) cerebral hyperæmia, (2) cerebral anæmia, and (3) irritation of the cerebral plasma itself, let us now consider how these morbid factors are most scientifically and speedily met at the bedside; and how, more particularly, those distressing conditions of engorgement, which are so baneful an item in the causation of a certain form of cephalalgia, are best overcome.
